Step-by-Step Solution

Introduction to Contraception\nAn ideal contraceptive should be user-friendly, easily available, effective, and reversible with least or no side-effects. It should in no way interfere with the sexual drive, desire, and/or the sexual act of the user. Various methods of birth control are broadly categorized into natural, barriers, IUDs, oral pills, injectables, implants, and surgical methods.

Detailed Categories of Contraception Methods

  1. Natural / Traditional Methods:

    • These methods work on the principle of avoiding chances of ovum and sperm meeting.
    • Periodic Abstinence: Couples avoid or abstain from coitus from day 10 to 17 of the menstrual cycle when ovulation is expected.
    • Withdrawal or Coitus Interruptus: Male partner withdraws his penis from the vagina just before ejaculation so as to avoid insemination.
    • Lactational Amenorrhea (absence of menstruation): Based on the fact that ovulation does not occur during the period of intense lactation following parturition. This method is effective only up to a maximum period of six months.
  2. Barrier Methods:

    • In these methods, ovum and sperms are prevented from physically meeting with the help of barriers.
    • Condoms: Barriers made of thin rubber/latex sheath used to cover the penis in males or vagina and cervix in females, which also help in preventing STIs.
    • Diaphragms, Cervical caps, and Vaults: Barriers made of rubber that are inserted into the female reproductive tract to cover the cervix during coitus.
  3. Surgical Methods (Sterilization):

    • Also called terminal methods, these are advised for male/female partners as a terminal method to prevent any more pregnancies.
    • Vasectomy: A small part of the vas deferens is removed or tied up through a small incision on the scrotum in males.
    • Tubectomy: A small part of the fallopian tube is removed or tied up through a small incision in the abdomen or through vagina in females.
